comment Use the pseudoinverse to find the conic section of best fit to the data
I added a section to address the method you tried in your comment.

comment Change of variables in maple
Maple's subs command is a syntactic replacement mechanism, not a mathematical one, and is commonly overused. You might get by using three nested calls to algsubs instead (using your rules one at a time). Ie, algsubs(rule502,algsubs(rule501,algsubs(rule500(...))). Or you could try simplify(...,{rule500,rule501,rule501}) to simplify with side-relations. Please note that your question is not about math and is off-topic here. Better to post it at stackoverflow or mapleprimes.com and also more polite to include your expressions in plaintext Maple syntax for copy & paste.

comment Using the pseudoinverse to find the linear combination of functions?
I've added more detail about M and C. I used Maple 18.01. You haven't yet written which version you're using.

comment Why is Maple not simplifying this expression
You are missing multiplication symbols between h and opening parentheses. As you write it those subexpressions are applications of function h and not the same as h*(...).

comment Maple - Find all intersecting points
Questions more related to "how do I do this in Maple" rather than the underlying mathematics are better suited to stackoverflow or the www.mapleprimes.com forum. Or, are you wondering whether you could get exact rather than floating-point results, or whether you do need to qualify your question with finite bounds on x?

comment System of linear algebraic equations in maple
Note that you can get something equivalent to what Equate gave above, by simply issuing the single command solve( {eq1, eq2}, [x1,x2,x3,x4] ) which returns a result with two of the 'xi' as the free parameters.
